My questions is this, what do you do with that Twin scroll solenoid ? I have plugged the vacuum port do I need to Unplug the solenoid or just leave it the way it is ? Can some one shed some Light. 1988 T2 S4 Street Port, stock.

 

are you trying to be legal? im running a full s5 turbo motor in my s4 n/a car. you could just delete the rats nest all together, and just run the s5 turbocharger.
